346 APPENDIX I 



The eastward progression of the tide wave along 

 the northern coast of Grant Land as shown by obser- 

 vations at Point Aldrich, Cape Sheridan, and Cape 

 Bryant. 



The great age of the ice found in Beaufort 

 Sea. 



Items of some importance in this connection, 

 but which cannot be regarded as established facts 

 are: 



The probable westerly courses taken by casks set 

 adrift off Point Barrow and off Cape Bathurst, the one 

 recovered on the northeastern coast of Iceland, the 

 other on the northern coast of Norway; 



The question suggested by Harrison whether or 

 not enough ice escapes from the Arctic to account for 

 the quantity which must be formed there if one were 

 to adopt the assumption of an unobstructed polar 

 basin. 



Taking various facts into consideration, it would 

 seem that an obstruction (land, islands, or shoals) 

 containing nearly half a million square statute miles 

 probably exists. That one corner lies north of Bennett 

 Island; another, north of Point Barrow; another, near 

 Banks Land and Prince Patrick Island; and another, 

 at or near Crocker Land. 



Meteorology. — Regular hourly observations of 

 the thermometer and barometer were carried on day 

 and night by the tide observers. 



A brief resume of the results obtained is given below, 

 together with a few taken from the Report of the Pro- 

 ceedings of the U. S. Expedition to Lady Franklin Bay 

 by Lieutenant (now General) A. W. Greely.
